Add newlib syscalls. 2018-05-25 12:31:38 +02:00			`.extern main`

Split out crt from wutnewlib to wutcrt. Can now optionally link newlib, stdc++, devoptab. 2018-05-27 13:12:49 +02:00			`.extern __init_wut`
			`.extern __fini_wut`

wutcrt: Setup a proper stack frame for _start. 2018-05-30 23:13:49 +02:00			`stwu 1, -0x14(1)`
			`mflr 0`

			`stw 4, 0x10(1)`
Add support for generating RPL files. RPL files are shared libraries (like a .dll file), as opposed to the RPX files which are executables (like a .exe file). Use rpl_main as defined in dynload.h like one would DllMain on Windows. 2018-05-30 22:56:18 +02:00			`cmpwi 3, 2`
			`beq unload`

			`load:`
